A good friend of mine, fellow Ham and SDFer, Larry D. Barr-K5WLF, has started a new technical blog that will be good to follow. The K5WLF Tech Blog
From the first post:
Welcome to the first post of the K5WLF Tech Blog. Unlike my other blog, The K5WLF Blog, wherein I ramble and discuss anything from computers to ham radio to film directing to ??, we’re going to stay focused here and just discuss technical issues. In the course of those discussions, we’ll talk about the tech stuff and we’ll discuss some of the history of electricity and electronics. We’ll also take a look at some of the pioneers who made it possible for us to have the technology we have today. Folks like Faraday, Ampere, Volta, Tesla, Edison, Westinghouse, DeForest, Marconi and so many more. I’ve created a special category called “The Great Ones” that you’ll see whenever there’s a post about one of them.
Here is an example of a Python CGI that I have running on my SDF.org website. It generates a ASCII Mandelbrot Fractal and allows for the user to change and zoom in the field of view. Granted, it is very low resolution being ASCII, but the main purpose was to demonstrate the use of Python for CGI purposes on SDF.org. (FOR FURTHER EXPLORATION): Since the SDF.org server Python package (v 2.6.5) has the PIL (Python Image Library) available, I can see no reason that true binary images of Mandelbrot fractals might not be produced and displayed on as pictures on the web page. UPDATE: As suspected, creating true graphical Mandelbrot fractals did in fact work out well. Here is a link to a Python CGI that uses PIL to create the images. Graphical Mandelbrot CGI
Here on SDF.org there are nearly 2000 clearly identified and active Amateur Radio operators. That is a great base of users from which to draw an active membership of the newly forming SDFARC – the SDF.org Amateur Radio Club. There has been a fair amount of interest shown so far, even with the relatively limited word that has been put out about it. It is hoped that this organisation will be able to be an international Amateur Radio Club that will serve the interests of Amateur Radio Operators who are members of SDF.org. We are planning on having nets, starting out by using echolink (see the growing list of echolink repeaters we are using: http://sdf.org/?tutorials/sdfarc_repeaters), but hope to expand our communications to also include HF, CW, and other modes. If you are a Ham and already an SDF.org member, please consider joining us. Find our discussions about SDFARC on the SDF.org shell bboard Amateur sig, or on the SDFARC webforum. If you are just a visitor to my blog but are interested. Please visit the WA5PB Ham Website to find out more about becoming a licensed Amateur Radio Operator. Also, please visit SDR.org to learn how to join the best online community on the Internet.

While visiting many fellow SDF.org websites, and while chatting with users on this system, I have come to really appreciate its international nature. To celebrate the spirit of global diversity found on SDF, I have added Google Language Translation to my MOTD blog and am working to add it on my webpages. vive la différence!
